'Please subscribe to higher plan to generate higher resolution videos'

I keep having this error on Generate from Template V2 despite being subscribed to the Heygen Scale API subscription and setting the dimensions to 720p.

data = {
        "test": False,
        "caption": False,
        "title": "video_title",
        "variables": {
            "script_here": {
                "name": "script_here",
                "type": "text",
                "properties": {
                    "content": text
                }
            }
        },
        "dimension": {
            "width": 1280,
            "height": 720
        }
    }
